The name "Malysh" is derived from the adjective "maly" (small) with the suffix -ysh, similar to names like "Danysh," "Pavlyykh," or directly from the Eastern Ukrainian appellative "malish," which means 'baby.' The personal name "Malysh" was already in use in Ukraine since the late 15th century. The first written record of this name dates back to 1456: "Maliszha" (OKZR III 79); in 1483: "Malyshъ" - a noble person from the south (Tup 242); in 1552: "Malyshъ" - a hired servant mentioned in Zhytomyr (Arch YZR VI II/1 149); in 1565: "Mytko, or Malysh" (Demchuk 19); in the 15th – 16th centuries, the name "Małysz" is also attested in the Halych and Lviv lands (Szulewska 19); in 1639: "Malisz" (Arch YZR VIII/2 75). Among the Zaporizhian Cossacks, eight individuals named "Malyshъ" served in 1649, for example, "Malyshъ Hrytskovych," "Malyshъ Myronenko," "Malyshъ Storozhenko," "Malyshъ Rudchenko," and "Malyshъ Shiyinsky" (RVZ 215, 217, 241, 257). The name "Malysh" is also mentioned later, for instance, in 1666: "Malyshъ Vasiliev," "Malyshъ Zinovyev" (PK 110). Patronyms derived from the name "Malysh" are noted relatively early. For example, in 1552: "Malyshonокъ" - a Київ citizen (Arch YZR VI II/1 114); in 1649: Cossack of the Cherkasy regiment Sidor "Malyshenъko" (RVZ 92); in 1669: Zaporizhian Cossack from the hetman Stepan "Malyshевъ" (Tup 632). The name "Malysh" was also popular in Russia until the 17th century (Tup 242) and in Bulgaria (Ilchev 317). The lexeme "Malysh" began to frequently appear as a surname in Ukraine from the 18th century.
